. My invention relates to improvements in hydrocarbon burners.

It isparticularly adapted to be used in a cooking stove, but it may be used in a heating stove or other place.

The object of my invention is to provide a compact and convenient arrangementof parts, which will enable the device to be v'inserted into the fire box of a cook stove through the end door thereof, and in which the operative parts are adapted for ready manipulation.

A further object of my invention is the provision of an improved collecting deflector of novel construction, which is adapted to collect and deect burning gas against a generator tube.

Still another object of my invention is to provide novel valve mechanism by which the operator of the burner may easily regulate the flow of gas or vapor.

My invention provides further a novel arrangement of 'valves by which the supply of liquid fuel may be independently controlled with relation to a drip pan and a generator tube.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates the preferred embodiment of my invention.

connected therewith.

Fig.' 6 isa cross section` on the line 6-6 1 designates ahorizontal casing which Specification of Letters Patent. Patented Oct', 23, 1917, Application led October 23, 1916. i Serial No. 127,135. l

is adapted to rest upon the grate-or bottom y of a fire box of a cook stove.

The casing 1 is provided witha horizontal longitudinal partition 3, Fig. 3, which extends from oneend of the casing to a point spaced apart from the other end of the casing and which divides the casing into an upper chamber and a lower chamber 4 and 5 which constitute respectively a burner chamber and a mixing chamber.

The burner chamber 4 is provided in its upper side with a plur'ality of transverse parallel, discharge slots or openings `6, through which the mixed vapor, or gas and air is discharged.

The burner chamber 4 and mixing chamber 5 communicate with each other at the right end of the casing 1, as viewed in Fig. 3. The mixing chamber 5 at the other end of the casing is provided with a flaring air inlet 7.

In said end of the casing 1 is secured one end of a longitudinal horizontal fitting 8, which is shown enlarged in Fig. 4, and which is provided with a longitudinal hole 9, therethrough which constitutes a passage,v for the gas or vapor and which is provided with an outlet 10 which discharges into the mixing chamber 5.

The outlet 10 is controlled by means of a 'valve comprising a` longitudinal rod 11 which is slidablymounted in the passage 9 and which is movable therein to and from a position closing the outlet 10.

The outer end of the valve 11 is provided with a vertical hole through which loosely extends a handle 12, the upper end of which is loosely pivoted by means of a screw 13 in the upper end of the handle to one end of a horizontal longitudinal link 14 which is fastened at its other end by a screw 15 to the upper side of the fitting 8.

A stuffing box 16 of ordinary construction encircles the valve 11 and has screw-threaded connection with the-outer end of the fitting 8.

The lfitting 8'is provided with an inlet 17 communicating with the passage 9 for sups1 plying the latter withgaseous fuel.

The upper side of the fitting 8 is provided-- with a screw-threaded hole in which is fitted a screw 18 constituting a stop member, the lower. end' of which extends into a 'transverse groove 19, which is provided in the upper side of the valve 11. The screw `18 serves to limit the movement' of the valve' the branches 32 and 33. rThese valves are 11 in both directions, thus preventingI the 29 against the two arms of the generator valve from being crowded into .the tapering outlet 10 and also preventing 'the handle 12 from swinging too far in the other direction.

Upon swinging the handle 12 to the proper position, the flow of vapor or gas into the mixing chamber 5 through the outlet 10 may be controlled.

A U-shaped generator tube 2O is disposed with its arms parallel with and adjacent to the burner chamber 4, so that the Haines from the slots 6 may heat said generator tube.

One arm of the generator tube 20 discharges into the passage 17 of the iitting 8.

The other arm of the generator tube 20 is fastened by a union 21 to a fitting 22.

Secured to said fitting 22 by a runion 23, is one arm of a U-shaped fuel pipe 24, which is disposed with one. arm above the other and thelower arm of which is disposed in a drip pan 25 mounted on the base 2 below the generator tube 20,l as shown in Fig. 1. The lower arm of the fuel pipe 24 is provided at its end with a cap 26, in the upper side of which is provided a discharge opening 27, arranged to discharge. oil through I the open bottom of a hollow rectangular collecting deflector 28, which has its ends pivotally mounted on the upper arm of the fuel ypipe 2,4. 'The upper side of the collectingv deflector 28 is provided with two longitudinal slots 29 which are adapted ,tolrespee Vtively discharge the vaporized fuel againstthe two arms-of the generator tube 20. In case that the generator tube becomes warped or sprung from its proper position in any manner, the defiector 23 may be swung so as to dispose the slots 29 in theV proper posi tion with relation to the arms of the generator tube 20.

' The fitting 22 is providedy with a vertical .passage 30, Fig. 5, which at its upper end communicates with a fuel supply pipe 31,' and which is provided with two lateral` branches 32 and 33 which respectively discharge into one arm of the generator tube.

20 and into the upper arm of the fuel pipe 24.

rlwoh valves are mounted in the fitting 22 and have screw-threaded connection therewith and are adapted to respectively close and-the burning oil heats the Ychambers 4' and 5. At the same time, vapor or burning gasis discharged through the deflector 28 nasales i and/is directed in passinglthrough the slots tube 20. When the'generator tube has become suiiiciently heated, the valves 34 and 11- are opened, the valve 35 having been closed afterisuiiicient oil has been-deposited beingdischarged through the pass'agefl'lv and the passage 9 into the mixing chamber 5, in which chamber 'it mixes with air which enters the inlet 7, Aand the. mixture then passes into the burner chamber 4 and escapes through the slots 6, following which it is ignited and keeps the generator tube20 hot and also effects its function of heating the stove. I I By having the burner chamber 4 and mixing chamber 5 separated only by the partition 3, lvthe burner chamber more readily heats the mixing chambere and at the saine time a compact structure .is afforded which is not liabie to; Warp and whichfhccupies a minimum bf space vertically inthe fire box' of the cool: stove. l. l

' TheA means provided ,for operating the valve 11 permits the operator of the co kstove to readily manipulate the valve wi h a poker or stick if desired, and if operated' with the hand, it may be done so quickly that the operator is not long closely exposed to the heat yof the stove.

l donot limit my invention to the 4structure shown and described, as modifications,
